For a glorious four days in April, two TV shows with madly devoted fan bases, yet divergent styles, will overlap: Mad Men, whose seventh season (part one) returns April 13, and Scandal, whose third season finale airs on April 17. In honor of that television eclipse, here's a definitive guide to the eight (eight!) actors who have appeared in both series, and how the characters they played on both shows stack up against each other. It's pretty bizarre to imagine the Mad Men and Scandal universes colliding, but who knows: Maybe the casting directors have a drinking game for every time yet another Mad Men alum ends up in Olivia Pope's office. (Defiance-sized spoiler alert for all seasons of Scandal and up until the fifth season of Mad Men.)
